Your rating being higher on Lichess doesn't mean that the competition is better, Lichess ratings just start higher, see https://lichess.org/page/rating-systems

On the contrary, there are more Grandmasters playing on Lichess (like the World Champion), and if you check your percentile on both sites, you'll most likely see that you're better than a higher percentage of chesscom users than Lichess - which would indicate that Lichess players are better on average.

And yes, I also think Lichess is superior to chesscom i nearly every way.
